How can I perform a bulk update using Django ORM?

How can I perform a bulk update using Django ORM?

You can use the update() method on a queryset to perform a bulk update. For example, MyModel.objects.filter(condition).update(field=value).

Can I update multiple fields at once?

Yes, you can update multiple fields by passing them as keyword arguments. For example: MyModel.objects.filter(condition).update(field1=value1, field2=value2).

What if I want to update based on a list of IDs?

You can filter by a list of IDs using the __in lookup. For example: MyModel.objects.filter(id__in=[1, 2, 3]).update(field=value).

Are there any performance considerations I should be aware of?

Yes, bulk updates are generally more efficient than updating records one by one, but be cautious with large datasets as it may lock the table.
